The human body is made up of two layers. the epidermis and the dermis.the epidermis is made up of two dead layer horny layer and granular layer.and the sensitive malpighian layer.
this serve to protect the inner structure in the dermis and are many structure including the sweat glands. the sweat duct and the sweat pores.that are directly involved in excretion of sweat from the body
HOW THE SKiN WORK IN EXCRETION
the sweat glands collect excess water. excess SALT and urea from the blood capillary in the dermis to form a salty liquid called sweat the sweat flow into the sweat duct through the concentraction of the muscles and passes out through the sweat pore.
the passing out sweat through the skin help to control the temperature of the body. it cause cooling. however if the sweat dries on your skin.
it may block the sweat pores and if bacteria settles on it. you may have body odour. this is why you must wash your body regulregularly
